"There are some things in life that will only be understood through words."

Winry is a very emotional, strong-willed and emphatic person who puts all her heart and effort into the things she does. Enthusiastic about machinery, Winry is most at home near cranking gears, whirring bearings and the smell of oil and becomes absolutely giddy when given the opportunity to interact with and learn about such things, causing Edward to mock her as an "engineering otaku" or a "crazy gearhead". She is stubborn and straightforward, often calling others out for their weaknesses and delusions. Though she shares this trait with Edward, Winry is a bit more tactful with her honesty and usually only displays this side of herself to her closest relations. Winry's stout heart allows her to make difficult and dangerous choices very easily so long as they coincide with her strong sense of duty and morality.

Otaku Trivia:

1) Winry's trademark bandana is colored green in the manga and 2009 anime, while in the 2003 anime, it's red, however, in the end of episode 51 she switches to a green one.

2) In a Brotherhood OVA Winry explains that the reason she has so many piercings in her ears is because Ed and Al gave her multiple pairs of earrings and Winry wanted to wear all of them.

3) On the cover page of Chapter 107, Winry is included putting her hand in the circle with the rest of the protagonists.
